SPECIFICATION formingpart of Letters Patent No. 309,037, dated December9, 1884.

Application filed April 10, 1884. (No model.)

To all whom, it may concern:

Be it known that I, CHARLES A. TARRAGON, of Portland, in the county ofMultnomah and State of Oregon, have invented anew and usefulImprovementin Brick-Machines, of which the following is a full, clear,and exact description.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1, Sheet 1, is a sectional rear elevation of my improved machine.Fig. 2, Sheet 1, is a side elevation of the same, parts being brokenaway. Fig. 3, Sheet 2, is a plan view of the same, partly in section,through the line 00 00, Fig. 1. Fig. at, Sheet 2, is a plan view of thegrate, the shaft being shown in section. Fig. 5, Sheet 2, is a sectionalplan view of the machine, taken through the line yy, Fig. 1. Fig. 6,Sheet 2, is a front eleva tion of the lower part of the machine.

The object of this invention is to provide a simple, effective, andconvenient machine for making bricks.

The invention consists in a briclemachine constructed with a verticalshaft placed in a vertical hollow cylinder, and provided with radialarms carrying teeth to break up the clay, and plates to force the claythrough a grate secured in and to the said cylinder, whereby the claywill be crushed as it passes down into the machine. WVith the lowerparts of the cylinder and shaft are connected a hollow grinding-cylinderhaving a tapered and corrugated inner surface, a cylinder having spiralcorrugations and radial wings, substantially as herein shown anddescribed, whereby the clay is crushed and ground as it passes downthrough the machine. end of the shaft, within a recess in the base ofthe machine, are attached curved wings to push the clay outthroughopenings in the said base at the opposite sides of its recess. Inthe ends of the base of the machine, opposite the side openings to therecess, are formed chambers, in which move carriages carrying moldshinged to rods attached to the ends of the said carriages and held erectby springs, so that the said molds can be readily brought into positionto receive clay and withdrawn To the lower end of a crank-shaft, D,having a pulley, D,

upon its outer end, to receive adriving-belt driven from a steam-engineor other convenient power. v

To the inner end of the crank-shaft D is at tached a miter-gear wheel,ll, the teeth of which mesh into the teeth of the miter-gear wheel L,attached to the upper end of the vertical shaft G. The upper part of theshaft G revolves in bearings in the frame 0, and its lower end revolvesin a bearing in the bottom of the recess H, formed in the upper middlepart of the base A below the lower end of the hollow eylinder'B.

To the opposite sides of the vertical shaft G, at or a little below thetop of the hollow cylinder B, are attached the inner ends of two radialarms, 1', which are made triangular in form, and are arranged with thecorrespond ing sides of the two arms in the same plane and with theirlower sides horizontal.

To the forward parts of the horizontal lower sides of the arms I areattached one or more knives or teeth, J, which are inclined downward andforward.

To the rear inclined sides of the arms I are attached the upper ends ofshort bars K, to the lower ends of which are attached plates L of such alength as to leave spaces of about half an inch wide between their endsand the shaft G and the shell of the hollow cylinder B.

The bars K are'made of elastic material, so that the plates L, shouldthey strike a lump of clay or other hard substance that they cannotbreak, will yield and pass over the obstruction.

To the shell of the hollow cylinder B, just below the lower edges of theplates L, is secured a grate, M, formed of parallel bars connected attheir ends by a rim fitting into the interior of the said cylinder B.

In the center of the grate M is formed a bearing, N, to receive theshaft G and keep the said shaft in position.

The clay is fed into the upper. end of the cylinder B through a spout,O, or by other suitable means, where it is worked .by the arms I, knivesJ, and plates L, and is forced by the said plates through the grate M,all lumps being broken up between the tops of the grate-bars and thesaid plates L.

In the lower part of the hollow cylinder B is secured a hollow cylinder,1?, the interior of which is tapered downward or made in the shape of aninverted truncated cone. The tapered inner surface of the hollowcylinder 1? is grooved, as shown in Fig. 5, to adapt it to grind theclay.

To the shaft G, in such a position as to be within the lower part of thegrinding-cylinder 1, is secured a wheel or cylinder, Q,which is tapereddownward or made in the form of an inverted truncated cone. The wheel orcylinder Q is made of such a size as to fit into the lower part of thegrinding-cylinder I, and upon its face are formed spiral corrugations toadapt it to grind the clay and at the same time feed the clay downward.

To the shaft G, at the top of the grindingwheel or cylinder Q, isattached a conical hub, R, to which are attached radial wings S, theouter edges of which are tapered downward to correspond with the taperof the inner surface of the cylinder 1?, so that the clay will be brokenup and fed downward between the outer edges of the said wings and thecorrugated inner surface of the said cylinder.

To the lower end of the shaft G, within the recess H of the base A, areattached curved wings T, to push the clay as it falls into the recess Houtward and force it through the openings U at the sides of the saidrecess II into the molds V. The molds V are placed edgewise with theiropen sides toward the openings U, and are hinged at their lower edges torods \V, attached at their rear ends to carriages X. The carriages X andmolds V are placed in passages a in the end parts of the base A, andhave longitudinal grooves Y formed in the opposite sides of their lowerparts to receive the guide cleats Z, attached to the opposite sides ofthe passages or chambers a. The carriages X are mounted upon wheels I)to cause them to move forward and back easily.

To the outer ends of the hinging-rod XV are attached the inner ends ofthe coiled springs c, the outer ends of which are attached to the outerends of the molds V. The springs c are made of sufficient strength toraise the molds V, when left free, into an erect position. Vith thisconstruction, as the filled molds come out of the chambers a, they areturned downward into a horizontal position, as shown at the right-handpart of Fig. 6, and discharge the bricks upon offbearing -boards, readyto be taken to the drying-yard. The outer ends of the molds V areprovided with handles (Z, for convenience in controlling them.

To the rear ends of the carriagesX are pivoted the forward ends of theconnecting-bars e, the rear ends of which are pivoted to the lever f,upon the opposite sides of and equally distant from the pivoting-pointof the said lever. The lever f is pivoted. to a bar, '5, attached to thebase A or other suitable support, and one end of the said lever f isextended, and to it is pivoted the end of a short connecting-bar, g, theother end of which is pivoted to the lower end of the lever h. The leverh is pivoted to a bar, 9', attached to the standard k, which is attachedto the base-A or other suitable support.

To the upper end of the lever 71 is pivoted the end of a shortconnecting-bar, Z, the other end of whiclris pivoted to the crank D ofthe crank-shaft D, so that the carriages X will be operated by therevolution of the crank-shaft D to carry the filled molds V outwardalternately to discharge the bricks and draw them inward to be againfilled. The carriages X have plates m attached to their inner sides, toclose the openings U and prevent the clay from being forced into thepassages a while the filled molds are being carried out, emptied, andreturned to the said openings U. I

The guard-plates m may be provided with friction-wheels to roll alongthe outer sides of the passages a and strengthen the said guardplateagainst the outward pressure of the clay.

The machinery may be provided with wheels, so that it can be readilymoved from pit to pit.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. In a brick-machine, the combination, with thevertical shaft G and its driving mechanism, and the vertical hollowcylinder B, of the arms I, downwardlyprojecting teeth J, anddownwardly-inclined plates L, and grate M, substantially as herein shownand described, whereby the lumps of clay will be crushed as they passdown into the machine, as set forth;
